Winnebago County, part of the 17th Judicial Circuit, is located in northern Illinois and is the seventh-most populous county in the state. Its county seat is Rockford, the third-largest city in Illinois. The Circuit Court of Winnebago County handles probate matters through its Probate Division at the Winnebago County Courthouse.
Probate cases in Winnebago County are managed at the courthouse in downtown Rockford. The 17th Judicial Circuit Court serves Winnebago and Boone Counties, and the Winnebago County Courthouse is the primary location for probate filings and hearings.
Most estates in Winnebago County proceed under independent administration, consistent with the statewide preference under the Illinois Independent Administration of Estates Act. This streamlined process allows the estate representative to handle routine matters without prior court approval. For smaller estates, the small estate affidavit option is available when personal property is valued at $100,000 or less (increasing to $150,000 for decedents dying on or after August 15, 2025) and no real estate is involved.
The standard 6-month claims period applies following publication of notice to creditors. All probate filings must be submitted electronically through the county's e-filing system.
